📌 Features

The program includes the following functions:

• ➕ Addition – Adds two numbers
• ➖ Subtraction – Finds the difference between two numbers
• ✖️ Multiplication – Multiplies two numbers
• ➗ Division – Divides two numbers (handles division by zero)
• 🔲 Square – Calculates the square of a number
• √ Square Root – Finds the square root of a number

📂 Code Overview

1. Addition

function calculateSum(num1, num2) {
  return num1 + num2;
}

2. Subtraction
function calculateDifference(num1, num2) {
  return num1 - num2;
  

3. Multiplication
function calculateProduct(num1, num2) {
  return num1 * num2;
}
4. Division (with error handling)
function calculateQuotient(num1, num2) {
  return num2 === 0 ? "Error: Division by zero" : num1 / num2;
}
5. Square
function calculateSquare(num) {
  return num ** 2;
}
6. Square Root
function calculateSquareRoot(num) {
  return Math.sqrt(num);
}
